I was thinking about epoxy or glue for the screwheads and then some double faced tape to hold the plate in place.

I used to have a roll of carpet tape, but I can't find it.


It's sort of thick.

I took the screws that I have and cut them down to almost 1/8", then used spacers to set the height of the dog-ears on the receptacle just above the tile.
The process took a lot of work, but the first one turned out looking and working well.

Thanks to everyone who contributed.
